Please, could you describe the bug briefly?
I know it is a build error. In this case, a log is appreciated.
Why have I not seen the build issue? Is it specific to a compiler?

This macro was defined twice.
On machines with kernel < 3.8, IFF_MULTI_QUEUE didn't exist, and thus
both definitions used different values.
